The present study examined the impact that attention to social comparison (SC) information may have on consistency in physical activity (PA) behaviors across genders.SC factors, including SC frequency, SC direction and trait tendency to compare (SCO) were assessed within the Dynamic Relapse Model (DRM) as markers of PA consistency within men and women. Participants were N=200 individuals engaging in physical activity at YMCA gym facilities. Data collection utilized cross-sectional methods including anthropomorphic data collection at the point of recruitment and online selfreport measures post-recruitment. High adherence to regular physical activity was observed, with participants reporting infrequent slips in PA (modal PA slips was 0).Participants reported engaging in upward and lateral SC most frequently, with downward SC being infrequently reported. Overall reported engagement in SC was intermittent; the modal frequency of SC engagement was "sometimes." Specific hypotheses were developed to explore the relationships between SC direction, SCO, gender and PA consistency outcomes. SC direction and frequency were not related to PA consistency.Gender differences were not observed in the frequency of SC constructs or PA iv vi consistency, however, a significant interaction was observed between gender and SCO; women's PA consistency was impacted by SCO to a greater extent than their male counterparts'. A decrease in PA consistency was observed at high levels of SCO in women, but not in men. Study findings suggest that SCO may be most impactful on
